Cl. 156-577 12 Claims ABSTRACT OF THE DISCLOSURE The rolling of the applicator of a dispensing device along a surface on which adhesive tickets are to be applied drives a mechanism that pulls a carrier tape, on which the adhesive tickets are supplied, from a supply roll, by causing a tension roll indirectly geared to the applicator roll to pull the carrier tape first around a take-off roll, also geared to the applicator roll, and then around the rounded edge of a guide vane, at which point the tickets carried on the tape are projected against the applicator roll and drawn under it. The tickets are separated from the carrier tape and then torn away from the succeeding tickets because the drive of the take-oil and tension rolls is such that the peripheral velocity of the applicator roll is higher than the velocity of the tape in the neighborhood of the guide vane.

This invention relates to a hand apparatus for dispensing and applying adhesive labels or other sticker tickets which are coated on one or both sides and are supplied on a carrier tape. The dispenser comprises a housing, a hearing for the roll of ticket tape, a takeoff roll, a guide vane and a tension roll. The hand dispenser is particularly adapted to dispense and apply adhesive tickets coated on both sides that are to be applied on a substrate either one by one or in successive group arrangements.

Dispensing devices are known in which adhesive tickets separated from each other only by a cut may be applied singly one after the other to a substrate. In the case of such devices the tape is drawn from its roll and around a guide by one or more tension rolls acting on the carrier tape after it has been separated from the tickets. The drive of the tension roll is provided by means of a lever movement from a tong-like extension of the dispensing device.

In the case of another known device the drive of the tension roll is provided by a driving roll designed to roll on the substrate, which then drives the tension roll. The tape is arranged to be pulled forward through the engagement of the driving and tension rolls.

The known mechanisms have the disadvantage that they either are technically and therefore economically wasteful or else require the user to exercise close attention, since he must not only take care that the applicator roll is correctly rolled on the substrate, but also that the drive roll is rolled on the substrate as well.

The dispensing device of the tong-carrying variety has the disadvantage that the tickets can be applied to a substrate only singly one after another. It is therefore not adapted to apply a series of tickets in an exact predetermined separation in a straight line succession on a substrate, since the user continually loses the aligment by the opening and closing of the tongs.

The previously mentioned roller-driven device is adapted for applying several tickets in succession with predetermined spacing only when the tickets are already arranged on the carrier tape with that spacing. If then occasionally only a single ticket is to be applied to a substrate, then this device has the disadvantage that individual tickets succeed each other on the carrier tape so 3,740,299 Patented June 19, 1973 closely that a second ticket readily follows the first and becomes partly applied to the substrate.

The known devices are not at all adapted for the dispensing and applying of adhesive tickets coated on both sides.

The problem to which this invention is directed is the provision of a simple, inexpensive hand-operated device for dispensing and applying adhesive tickets, by which adhesive tickets coated on both sides as well as those coated on one side can be dispensed and applied. In particular, the invention aims to provide a device for dispensing and applying adhesive tickets coated on both sides which are connected together on a carrier tape but are nevertheless arranged to be easily separable, without the provision in the device of a wasteful cutting mechanism.

The solution of the problem is found in a hand-dispensing device in which the applicator roll drives both the take-off roll and the tension roll and in which the peripheral velocity of the applicator roll is greater than that of the take-off roll and of the tension roll.

By means of the drive of the take-off and tension rolls, which draws the carrier tape around the guide vane, the result is then obtained that superfluous contrivances independent of the unwinding operation are avoided and, as a further result, the user can concentrate entirely on rolling the device along to apply the proper number of tickets.

The greater peripheral velocity of the applicator roll makes possible, moreover, that as the connected tickets unroll in their readily separable condition on the carrier tape, each in turn is torn off from the following ticket, whereby the provision of a cutting device is obviated. This arrangement, because the tickets then proceed over the applicator roll spaced one from the other, has the advantage that in the application of single tickets on a substrate the [following ticket is not accidently stuck on along with it. The arrangement has the further advantage that regardless of whether the tickets are arranged on the ticket ta-pe completely separated or easily sepanable, the user can tell when a single ticket has been released from the carrier tape, because he feels a slight kick arising from the difference in the respective peripheral velocities of the applicator roll and of the carrier tape in the neighborhood of the guide vane and the change of tension consequently produced when a ticket is torn off and no longer drags the applicator roll.

The dispenser is preferably so designed that, in addition, the peripheral velocity of the tension roll is somewhat greater than that of the take-off roll, but still smaller than that of the applicator roll. The effect is thus obtained that the ticket tape is always led tightly around the guide vane.

The drive of the take-off roll and of the tension roll preferably takes place by means of a gear on the applicator roll that engages an external ring gear that also engages the gear of the take-off roll, which in turn operates in connection with a gear fixed on the tension roll.

The differing peripheral velocities may be determined by differences in the diameter of the rolls in the case of equal gear ratios or by differing gear ratios in the case of equal roll diameter, or by some combination of both methods.

The periphery of the take-off and applicator rolls is preferably pro-vided with a silicon coating in order to prevent, in the case of rolls of tickets coated on both sides, sticking of the coated upper side of the ticket.

For the utilization of the dispenser with adhesive tickets coated on one side it is advantageous to provide leaf springs to press the tape against both the take-off and tension rolls. In the case of rolls of tickets coated on both sides the leaf spring working on the take-off roll is not necessary, hence this spring is preferably so arranged in the apparatus that it can easily be removed from its mounting stud.

In order to facilitate the loading of a new tape, it is advantageous to provide a lever With which the springs pressing against the take-01f and tension rolls can be disengaged. On the housing cover a projecting ridge with a bevelled edge is preferably provided which upon closingof the housing presses on an oblique surface of the lever, whereby the latter is moved from its disengaged position into its normal position, which results in applying the springs to the take-off and tension rolls respectively.

For the further explanation of the invention reference is made to the illustrative embodiment shown in the annexed drawings, in which:

FIG. 1 is a perspective view of a hand-operated dispenser with the housing cover removed;

FIG. '2 is an exploded perspective drawing of the dispenser without cover and without ticket roll;

FIG. 3 is a perspective view of a portion of the dispenser and of the housing cover;

FIG. 3A is a section along lines 3A-3A of FIG. 3, and

FIG. 4 is a perspective view of the dispenser in use.

The dispensing device comprises a lower housing unit or base 1 and a cover 11. On the base 1 is arranged a bearing 3 for the ticket roll 2. Bearing pins for the take-off roll 4, the applicator roll 5 and the tension roll 6 are also provided. The take-01f roll 4, the applicator roll 5 and the tension roll 6 are each provided with a gear. The gears of the take-off roll 4 and of the tension roll 6 are positioned in direct engagement. The gears of the applicator roll 5 and of the take-off roll 4 are connected with each other by a ring gear 16 which is seated on an annular bearing 17 carried by base 1.

Two leaf springs 7 and 8, which press against tension roll 6 and take-off roll 4 respectively are removably arranged in slits of mounting studs that are fixed on base 1. Also on base 1 a guide vane 9 is mounted in the neighborhood of applicator roll 5.

The disengaging lever 10 is shiftably mounted by slit apertures 10c and 10d on bosses 14 and 15 which are carried by base 1. The slit 10d has a lateral cut-out into which lever 10 is laterally movable for seating. On lever 10, pins 10a and 1012 are so arranged that they engage leaf springs 7 and 8 when lever 10 is actuated to disengage the springs from the take-off roll 4 and the tension roll 6 respectively. The lever 10 is further provided with a grip portion 10e at right angles, which has an oblique surface 10 On the inside of the cover above the handle 10e a projecting ridge 12 with an oblique edge is arranged which presses against the oblique surface 10 of the lever grip 102 when cover 11 is closed over base 1 and thus moves lever 10 out of its seat in the lateral cut-out of slit 10d back into normal position, whereby the springs 7 and 8 again are allowed to press against take-off roll 4 and tension roll 6 respectively.

Silicone rubber rings 13 are seated on take-off roll 4, applicator roll 5 and tension roll 6.
